AC unit freezing up
Answer: call a hvac technician.
Ice forming on your air conditioner's evaporator coil or refrigerant lines signals restricted airflow or a refrigerant issue. Running a frozen unit can damage the compressor — the most expensive component. An HVAC technician can safely thaw the system, find the cause (dirty filter, low refrigerant, or a failing blower), and prevent repeat freeze-ups.
